GAR'BID-LAMP.

To all whom t may concern: .Be it known that I, STANLEY PrU'r, a citiresiding at Glen Richey, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in Carbid-Lamps, of which the following is a specification.

The invention has for an object to pro- Yvide a simple and economically manufactured form of acetylene generating lamp suitable for use upon bicycles and motor vehicles. A particular purpose is tol give a satisfactory structure in such lamps which is adapted to be started quickly, and in which the renewal of water and carbid may be accomplished with facility. y Additional objects, advantages and features of invention will appear from the construction, arrangement and combination of parts hereinafter described and shown in the drawings representing one of the possible embodiments of my invention, wherein- Figure 1 is a vertical sectional view of a klamp constructed 1n accordance with my invention, y

Fig. 2 is an enlarged view of the construction of the regulator parts,

Fig. 3 is a fragmentary top view.

There is'illustratcd a lamp comprising an upper reservoir and headlight construction 10, which includes a body portion 11 of substantially cylindrical form, disposed upon a horizontal axis, the side portion and rear end portion 12 being pressed integrally from one blank of plastic metal. The front end of the receptacle is closed by means of a reiector element 18 litted snugly therein, a suitable lens 14: being held over the end of the receptacle which projects some distance beyond the reflector 18, by means of a screw cap 15.

Ally mounting the lamp upon a mounting being secured upon 12 of the reservoir receptacle.

A tubular stem 17 is secured upon the lower side of the receptacle 11 having threads thereon, and upon this there is engaged an interiorly threaded neck portion 18 of the carbid container 19 which may be of any familiar construction, in the present instance shown as substantially bottle shaped, including the neck portion 18.

From the upper part of the stem 17 a suitable pipe 20 leads to the space immediately before the reiector 13, the outer suitable means is provided at 16 for bracket, this the rear end Specification of Letters Patent.

`end of the pipe being provided with a suitable burner 21.

Through the lower side ofthe receptacle 11 there is extended a water feed pipe 22, f which also extends upwardly across the resrervoir to a movable spring mounting subsequently. to be described. This pipe is provided with suitable apertures therein adjacent the lower part of the' receptacle 1l, and may also have a suitable'wick 23 therein. lt is considered desirable that this pipe may be constructed so that its upper end may move vertically, for opening and closing of the upper end thereof as will be subsequently described, and' in order to facilitate this, the pipe may be shaped as shown at 24, including a helix, or itvmay be made in two sections connected by a small piece of rubber tubing or the like, the last named detail not being illustrated, as being suiiiciently obvious.

The upper end of the pipe 22 is secured of a small spring 25, which in turn is mounted upon a heavier spring 26, secured to the inner side of the receptacle 11 at its upper part. For the proper functioning of the device the heavier spring 26 is apertured to permit the pipe to pass therethrough freely for vertical movement the spring 25 being attached to the larger spring the latter, extending inwardly thereover. The larger spring is the heavier or stronger of the two, for reasons which will become apparent. On the outer end of the spring 26 a valve seat 27 is mounted, adapte-d to seat in an opening 28 in the upper side of the receptacle 11 when the spring 26 is at the upper limit of its movement. A small push button 29 is mounted upon the spring 26, and located without the receptacle 11, pressure upon which will depress the spring 26, moving the valve 27 to open position, as will readily appear. The button 29 may be mounted upon the valve 27, by means of a very small stem 30, so that when the valve is open the stem of the button 29 does not materially diminish the clear way through the opening. Upon the top of the receptacle 11 a small annular seat 31 is provided, and the upper end of the pipe 22 is constructed to engage snugly around this seat, the receptacle 11 having a suitable opening therethrough leading through the opening in the seat 31. Upon the outer side of the receptacle 11 a regulator valve is provided, in

the Y i-o-rm of allsiriallI free end adapted to t snugly over the open- 1l to the carbid container 19, as Will become apparent.: The pipe-22 is provided with holes 33 adjacent its lower end through which Water in the lreceptacle maygain accessto the Wick 23, and ifdesired additional holes: may be formed in lthevupper part of the pipethrough Which airdrawn through the seat 3l may gain access to the upper part of the receptacle l1.

In kuse, the carbid. container 19: r being properly filled and the receptaclellpartly filled with Water, when it is desired to start the lamp, in order toy avoid .delay in Waiting for the generation of suflicientpressure Vin the carbid container tosupply gas as desired to the burner 2l, the button 29 is depressed, Which admits a large quantity of air directly to thelcontainer: 1l, permitting a rapidv flow of Water from-the container through the pipe 22 to thecarbid, and after -depression of the button 29 for a short time,

it is released, and the lamp allowed to operate automatically, the flow ot water from the receptacle l1 to thecontainer 19 being regulated by means of the valver32.

The receptacle ll maybe provided With a customary form of lling opening and closure as at 36.
